“…Therefore, fuel pressure must be raised from 25 psig to about 115 psig at ambient temperature to supply the engine. The majority of LNG vehicles currently use a saturated LNG conditioning system [1]. The most common bulk condition method raises the pressure (without a pump) at the station by warming the fuel.…”

In addition to their significant environmental impacts, medium-duty and heavy-duty (HD) vehicles are high volume fuel users. Development of such vehicles, which include transit buses, refuse trucks, and HD Class 6-8 trucks, that are fueled with natural gas is strategic to market introduction of natural gas vehicles (NGV). Over the past five years the Department of Energy's (DOE) Office of Heavy Vehicle Technologies (OHVT) has funded technological developments in NGV systems to support the growth of this sector in the highly competitive transportation market. The goals are to minimize emissions associated with NGV use, to improve on the economies of scale, and to continue supporting the testing and safety assessments of all new systems. This paper provides an overview of the status of major projects under a program supported by DOE/OHVT and managed by Brookhaven National Laboratory. The discussion focuses on the program's technical strategy in meeting specific goals proposed by the NGV industry and the government. Relevant projects include the development of low-cost fuel storage, fueling infrastructure, and HD vehicle applications.

“…The disadvantage by doing so is that the density is reduced at the higher pressure and therefore less fuel can be delivered to the vehicle tank. With such an arrangement, it has been reported that vehicle range can decrease by about 11% [1].…”
